fix: add label to stop e2e tests timing out

[maghirardelli]

Issue #, if available:

Description of changes: the e2e test timed out I think because it didn't wait for the proper button to render before it tried to find the button to click. I now named the button so it should wait for that button to render before it checks it's contents. This did not timeout in my local or dev tests so I hope it works in the pipeline so everything can get to mainline
